I took Mom back to her primary physician for a follow up visit. It turns out she has severe sleep apnea and will need a CPAP mask to sleep. They did a 3 night in home study and found that she had many episodes every night. It turned out she stopped breathing around a hundred times a night, and for up to nearly 2 minutes! The doctor thinks that may be causing a lot of her problems. I can't imagine an 81 year old woman holding her breath for 2 minutes, yet she was doing it while she slept. It's amazing she woke up. The doctor said if you snore you should be tested for sleep apnea. I think we'll get Al tested pretty soon because he snores a lot.
We have occasionally noticed a faint propane odor in the motor home when we turn on the water heater. I don't keep it on all the time, just before we want a shower, or I need to wash dishes. We checked the fittings and found a small leak. We tightened it, but we're still noticing the smell. We've tried to trace the water heater propane line, but it goes under the floor and we can't get at any connections in that area. Now the propane detector has started to sound too, so it's even more alarming. I think the detector is working properly because when it sounds, I also smell propane.
I found a mobile Rv repairman that was recommended to us. He's coming this morning. In the meantime, we're not using the hot water heater. Hopefully he will be able to find the problem and repair it without us having to take the motor home into a shop. It's much more difficult with animals.
